fig. 2 is a schematic view of the structure of the anti-skid thread section of the present invention.

In the figure: 1. a hollow needle tube; 2. a limiting ring; 3. a movable rod; 4. a sliding sleeve; 5. a needle tail tube; 6. a needle tip body; 7. an anti-skid pattern section; 8. a thread groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a bone traction needle of adjustable anti-skidding line section, including hollow needle tube 1, the left and right ends of 1 inner chamber of hollow needle tube all is provided with vertical section for the spacing ring 2 of L shape, spacing ring 2 internalization is pegged graft there is the movable rod 3, the 3 relative one ends of two sets of movable rods are provided with sliding sleeve 4, 4 inner walls of sliding sleeve are provided with interconnect's screw thread section with 2 outer walls of spacing ring, 4 right sides of left side sliding sleeve are provided with the external screw thread post, 4 left sides of right side sliding sleeve are provided with external screw thread post assorted screw thread blind hole, 3 left sides swing joint of left side movable rod have needle tail pipe 5, 3 right-.

As shown in fig. 2, the middle part of the outer wall of the hollow needle tube 1 is provided with an anti-skid section 7, the length of the anti-skid section is one third of that of the hollow needle tube 1, the traction force needs to be frequently adjusted during bone traction, and the anti-skid section 7 can prevent the bone traction needle from axially sliding;
